Phenotypic improvements of the main traits over generations for (A) average body weight at day 21 (BW21); (B) average body weight at day 42 (BW42); (C) feed intake (FI); (D) feed conversion ratio (FCR); (E) average interval between meals (AIBM); (F) visit duration (VD); (G) meal duration (MD); (H) number of visits per day (NV); (I) number of meals per day (NM); (J) total feed time (TFT); (K) meal feed intake (MFI); and (L) daily feeding rate (DFR). Violin plot shows the overall distribution of phenotypic value, and box plot shows the median of different traits over generations. Most recent 3 generations data were used to compare phenotypic improvements.
